You will not only save money on your energy bills with this tankless unit, but there will also be no more late-night showers because your kids had used all the hot water before going to bed. You would be able to use hot water any time, as much as you want and need.

The heat exchanger and the construction of this unit are of commercial-grade, ensuring durability even for commercial use. Thanks to its sleek design, Rinnai r94lsi can be mounted in any room. It will not take much space at all.

Reviews:

Here is a helpful review from B. Thompson, who was very satisfied with this water heater:

I installed Rinnai R94LSi by myself. It shipped with everything I needed including the vent kit. I did all the electrical, plumbing and natural gas work myself. So far, the unit has provided enough hot water that we have never run out of water. We can do dishes, run the laundry and take a shower at the same time. My friend was so impressed that he ordered the same exact model. Our gas bill did go down slightly and we will get an energy star credit on our tax bill this year for the purchase price. Rinnai has a very satisfied customer here. (B. Thompson)

Here is another happy customer’s review we found on YouTube. It seems this buyer has installed the Rinnai R94LSi heater by himself. It shows that it can be done, but we do not recommend the DIY approach if you don’t have any plumbing skills.
